Scaling up climate services for agriculture in Mali Initial findings from piloted implementation of PICSA approach in Africa RISING project intervention zone, southern Mali

The Participatory Integrated Climate Services for Agriculture (PICSA) approach, designed by the University of Reading (UoR), focuses on improving farmers' livelihood and resilience against the effect of climate change. It provides farmers with accurate, locally specific climate and weather information; coupled with diverse, locally pertinent options for crops, livestock and other livelihood activities; and the use of participatory planning tools to improve and enlighten their decision making based on their individual situations. PICSA is a step by step approach, primarily designed for field extensionists to help them integrate new tools in their activities with farmers and improve the efficiency and impact of those activities on farmer's enterprises

Uptake of Climate-Smart Agricultural Technologies and Practices: Actual and Potential Adoption Rates in the Climate-Smart Village Site of Mali

Understanding the level of adoption of Climate-Smart Agriculture (CSA) technologies and practices and its drivers is needed to spur large-scale uptake of CSA in West Africa. This paper used the Average Treatment Effect framework to derive consistent parametric estimators of the potential adoption rates of eight CSA technologies and practices in the Climate-Smart Village (CSV) site of Mali. A total of 300 household heads were randomly selected within the CSV site for data collection. Results showed significant differences in the observed and potential adoption rates of the CSA technologies and practices (drought tolerant crop varieties, micro-dosing, organic manure, intercropping, contour farming, farmer managed natural regeneration, agroforestry and climate information service). The most adopted technology was the organic manure (89%) while the least adopted was the intercropping (21%). The observed adoption rate varied from 39% to 77% according to the CSA options while the potential adoption rates of the technologies and practices ranged from 55% to 81%. This implies an adoption gap of 2% to 16% due to the incomplete diffusion (lack of awareness) of CSA technologies and practices which must be addressed by carrying out more actions to disseminate these technologies in the CSV. Results showed that education, number of workers in the household, access to subsidies, and training have a positive effect on the adoption of most of the CSA technologies and practices. The adoption of drought tolerant varieties and micro-dosing are positively correlated with access to subsidies and training. The study suggests that efforts should be focused concomitantly on the diffusion of CSA options as well as the lifting of their adoption barriers

Transforming Food Systems in Africa under Climate Change Pressure: Role of Climate-Smart Agriculture

Low-income producers and consumers of food in Africa are more vulnerable to climate change, owing to their comparatively limited ability to invest in more adapted institutions and technologies under increasing climatic risks. Therefore, the way we manage our food systems needs to be urgently changed if the goal is to achieve food security and sustainable development more quickly. This review paper analyzes the nexus “climate-smart agriculture-food systems-sustainable development” in order to draw sound ways that could allow rapid transformation of food systems in the context of climate change pressure. We followed an integrative review approach based on selected concrete example-experiences from ground-implemented projects across Africa (Ghana, Senegal, Mali, Burkina Faso, in West Africa, Ethiopia, Kenya, Rwanda, and Tanzania in East Africa). Mostly composed of examples from the Climate Change, Agriculture, and Food Security (CCAFS) Research Program of the CGIAR (former Consultative Group on International Agricultural Research) and its partners, these also included ground initiatives from non-CGIAR that could provide demonstrable conditions for a transformative agriculture and food systems. The lessons learnt from the ground implementation of climate-smart agriculture (CSA), in the African context, were instrumental to informing the actions areas of the food-system transformation framework suggested in this paper (reroute, de-risk, reduce, and realign). Selected CSA example-cases to inform these action areas included 24 initiatives across Africa, but with a focus on the following studies for an in-depth analysis: (1) the climate-smart village approach to generate knowledge on climate-smart agriculture (CSA) technologies and practices for their scaling, (2) the use of climate information services (CIS) to better manage climate variability and extremes, and (3) the science–policy interfacing to mainstream CSA into agricultural development policies and plans. The analysis of these examples showed that CSA can contribute driving a rapid change of food systems in Africa through: (1) the implementation of relevant climate-smart technologies and practices to reroute farming and rural livelihoods to new climate-resilient and low-emission trajectories; (2) the development and application of weather and climate information services (WCIS) that support de-risking of livelihoods, farms, and value chains in the face of increasing vagaries of weather and extreme events; (3) the use of climate-smart options that minimize waste of all the natural resources used for growing, processing, packaging, transporting, and marketing food, and therefore mitigating the carbon footprint attached to this food loss and waste; and (4) the realignment of policies and finance that facilitate action in the four proposed action areas through the identification of news ways to mobilize sustainable finance and create innovative financial mechanisms and delivery channels

Perspectives: Legislating change

About 80% of West Africans live in rural populations that mainly depend on rain-fed, cereal-based subsistence agriculture. These areas are highly vulnerable to climate variability. The increasing frequency and severity of climate extremes — primarily drought — have led to food crises in the sub-Saharan Sahel region. Although existing technologies and practices can mitigate agricultural risk, farmers need access to accurate long- and short-term weather forecasts so they can utilize these measures more effectively. One solution is localized seasonal climate forecasts for farmers. Partners from CCAFS in West Africa have recently tried such an approach in the Kaffrine district in central Senegal. To help ease the transition from traditional forecast practices, we presented the new information to farmers alongside discussions about established methods. Farmers in Kaffrine were able to develop adaptive techniques from climate information and choose a good strategy for improving yield during dry and wet seasons

Climate information use implications for climate risk mitigation in West Africa

With projections of a 70 percent increase in demand for staple cereals by 2050 in order to feed the growing human population (FAO, 2010), combined with the current declining per capita food production and a dwindling natural resource base, ‘feeding West Africa’ and increasing the resilience of livelihood systems may be well beyond reach. This has been attributed to multiple factors such as land tenure challenges, declining soil fertility, poor markets, climate hazards and variability, inadequate funding and poor infrastructural development (Ouedraogo et al, 2016; Partey et al, 2016). The current state of food insecurity and poor rural livelihoods are expected to be further exacerbated by climate change and variability which has emerged as one of the major threats to development in West Africa (Zougmoré et al, 2016)..

The value and benefits of using seasonal climate forecasts in agriculture: evidence from cowpea and sesame sectors in climate-smart villages of Burkina Faso

This infonote summarizes initial findings of a project entitled “Impact of communicating seasonal climate forecasts to cowpea and sesame farmers in Yatenga region, North Burkina Faso’” undertaken during the 2014 main agricultural season by scientists from the CCAFS West Africa programme and the Institut de l’Environnement et de Recherches Agricoles (INERA), Burkina Faso. Sesame is a cash crop promoted in recent years to respond to a growing global demand. Quite versatile and produced across the country, yields remain low with an average of 300-350kg/ha. National production was estimated at around 60,000 tons in 2012, mostly for export. Cowpea is a key legume crop, mostly cultivated by smallholder farmers in intercropping with cereals (95%). Yields are low (around 300kg/ha) while it could reach 1,500kg/ha in monoculture. Just a minority (5%) of farmers use modern inputs (improved seeds, fertilizer) and market their grain for the regional market. This project aims at assessing: The effect of climate information services on farm productivity and incomes for cowpea and sesame farmers in the Yatenga region; Farmers’ willingness to pay for such climate information services Lessons learned for potential scaling up of communicating climate forecasts services in the cowpea and sesame sector as a way to improve farmer climate resilience and productivity. Such studies are also being carried out in climate-smart villages in Senegal (Kaffrine region)

Why Promote Improved Fallows as a Climate-Smart Agroforestry Technology in Sub-Saharan Africa?

In the literature, a lot is discussed about how agroforestry can achieve the mitigation, adaptation and productivity goals of climate-smart agriculture (CSA). However, this may be relatively too broad to assess the trade-offs and synergies of how specific agroforestry technologies or practices achieve the three pillars of CSA. Here, we provide an overview of how improved fallows (an agroforestry technology consisting of planting mainly legume tree/shrub species in rotation with cultivated crops) may achieve the goals of climate-smart agriculture in Sub-Saharan Africa (SSA). Our review showed that improved fallow systems have real potential to contribute to food security and climate change mitigation and adaptation in SSA. Under proper management, improved fallows can increase maize yields to about 6 t ha−1, which is comparable to conventional maize yields under fertilization. This is attributed to improved soil fertility and nutrient use efficiency. Although data was generally limited, the growing literature showed that improved fallows increased soil carbon sequestration and reduced greenhouse emissions. Further, as a multiple output land use system, improved fallows may increase fodder availability during dry periods and provide substantial biomass for charcoal production. These livelihood options may become important financial safety nets during off seasons or in the event of crop failures. This notwithstanding, the adoption of improved fallows is mainly in Southern and Eastern Africa, where over 20,000 farmers are now using Sesbania sesban, Tephrosia vogelii, and Cajanus cajan in two-year fallows followed by maize rotations. Land tenure issues, lack of social capital, and improved germplasm and accessions of fallow species have been cited as constraints to scaling up. However, development of seed orchards, nursery development, and the willingness of policy makers to create a policy environment that addresses market failures and alleviates disincentives should improve adoption and future scaling up

Candidate fodder trees and shrubs for sustainable ruminant production in northern Ghana

A survey was done to document preferred browse plants and farmers’ knowledge about them for sustainable ruminant production in northern Ghana. The study was done in Jirapa and Lawra Districts of Upper West Region of Ghana. A questionnaire was used to interview 50 farmers per district. Tables and graphs were drawn to summarize results. Ruminant production was a predominantly male occupation (p=0.032). It was also in the domain of the lowly educated (p=0.003). Ninety-seven percent (97%) of the respondents had goats with about half of them having sheep and 17% owning cattle. The overriding (99%) reason for rearing ruminants was to serve as a source of income. In the dry season, ruminants were kept on free range. In the wet season, small ruminants were tethered with or without feed supplementation. A total of 34 browse plants were identified and the most frequently browsed were Fadherbia albida, Ficus sycomorus gnaphalocarpa, Afzelia africana, Pterocarpus erinaceus, Combretum molle and Annona senegalensis. Paramount among the challenges faced by the owners were limited grazing land, feed scarcity and theft. Apart from being fodder sources, the identified browse species were soil improvers, medicinal and human food sources. All respondents grew crops and the most frequently cultivated crops were groundnut, maize, cowpea, bambara groundnuts, sorghum, millet, rice and yam in this decreasing order. Ninety percent (90%) of the respondents fed crop residue to their animals, with the commonest, groundnut haulm, fed by about 80% of the respondents. Twenty-eight different types of trees/shrubs were identified on respondents’ farms

Closing the Gap between Climate Information Producers and Users: Assessment of Needs and Uptake in Senegal

West Africa is a very vulnerable part of the world to the impacts of climate change due to a combination of exposure and low adaptive capacity. Climate change has induced an increase in rainfall variability which in turn has affected the availability of water resources, ecosystem services and agricultural production. To adapt to the increased aridity, farmers have used indigenous and modern coping strategies such as soil and water conservation techniques, the use of drought-tolerant crops and varieties, crop diversification, etc., and lately, climate information services (CIS). The latter, according to the discourses, has positively contributed to suitable decision-making in terms of farming, pastoral and fishing management systems. However, the scientific documentation of the engagement approaches, the uptake of the CIS and the ways the delivered information is being used, as well as feedback from the users, is lacking. Additionally, in most of the cases where CIS are introduced, the disconnect between the users and producers of the CIS seems to undercut large-scale uptake. The objective of this paper is to examine the approach used to involve stakeholders in the CIS uptake process in Senegal. We analyzed the experiences and lessons learnt in the country where various CIS products were introduced using participatory methods (stakeholder consultations, interviews, field demonstrations, training workshops, etc.) and innovative stressors (SMS, voice messages, radios, mobile applications, etc.) to effectively involve producers, technicians and policy-makers. Results showed that 16 relevant CIS have been produced out of 27 identified by the various users; 11 CIS diffusion channels have been developed out of 13 requested; 27 climate advisory bodies (MWGs) have been created in 27 districts out of 30 districts in the study zone; about 6800 users have been trained directly and indirectly to effectively use CIS and about 8500 people are receiving CIS via SMS, voice messaging and emails. The opportunities for CIS uptake as well as the challenges that may impede the long-term sustainability of CIS upscaling in the country are highlighted. Recommendations that will improve and sustain the governance system of CIS in Senegal and the rest of West Africa include the involvement of private sectors in the chain of production, delivery and training, and the inciting of producers to largely subscribe to the weather-based index insurance

Assessing the Climate-Smartness of the West Africa Agricultural Productivity Programme (WAAPP): What can we learn from Benin, Guinea, Niger, Togo and Chad projects?

Agriculture is the most important sector of the national economies in West Africa. However, the agricultural sector is faced with numerous challenges (declining soil fertility and land degradation, adverse climate change manifestations, demographic pressure, market instability and incidence of crop pests and diseases, etc.), compromising its ability to be a driving engine out of food insecurity and poverty. With the growing challenge of climate change and variability in West Africa, the agricultural production and food systems must undergo significant transformations to meet the interlinked challenges of achieving sustainability, increasing food security and responding to climate change. Climate-smart agriculture (CSA) is proposed as a solution to transform and reorient agricultural systems to support food security under the new realities of climate change
